Function
Pin
Name
Function except a port function
Apply voltage of power source to VCC, and 0 V to VSS.
(As for VCC, refer to the recommended operating condition)
Connect to Vss.
Reset input pin for active “L”.
Input and output pins for the main clock generating circuit.
Connect a ceramic resonator or a quartz-crystal oscillator between the XIN and XOUT pins to set the
oscillation frequency.
If an external clock is used, connect the clock source to the XIN pin and leave the XOUT pin open.
A feedback resistor is built-in.
Input 0
≤ VL1 ≤ VL2 < VL3 voltage.
LCD common output pins.
8-bit input port.
CMOS compatible input level.
1, 2, 4 or 8-bit input and 8-bit pull-down can be programmed.
LCD segment output pin.
8-bit I/O port.
CMOS compatible input level.
CMOS 3-state output structure.
1-bit input/output and pull-down can be programmed.
5-bit I/O port.
CMOS compatible input level.
CMOS 3-state output structure.
1-bit input/output and pull-up can be programmed.
Analog input pins for A-D converter.
When these pins are used as ADKEY pins, the input
voltage of ADKEY pin which is input “L” level is A-D
converted automatically.
4-bit I/O port.
CMOS compatible input level.
CMOS 3-state output structure.
1-bit input/output and pull-up can be programmed.
8-bit I/O port.
CMOS compatible input level.
CMOS 3-state output structure.
1-bit input/output and pull-up can be programmed.
5-bit I/O port.
CMOS compatible input level.
CMOS 3-state output structure.
1-bit input/output and pull-up can be programmed.
